ANALYSIS OF UNCERTAINTIES IN DYNAMIC THERMOPHYSICAL MEASUREMENTSE. V. Chernukho UDC 536.083:681.2 A technique of analyzing the dependence of the uncertainty of results as applied to a thermophysical experiment is presented. The dependence of the uncertainty of the result of investigation of a sample under a temperature change on the number, uncertainty, and place and moment of experimental sampling is investigated. A comparative analysis of several approaches to solution of this problem is given. A. V. Luikov Heat and Mass Transfer Institute, National Academy of Sciences of Belarus, Minsk, Belarus.
